E20 High Your boiler has lost its ability to accurately measure the temperature of the water circulating through your radiators, causing the system to stop working for safety.
E28 High Your boiler has detected a problem with the sensor that monitors the temperature of the exhaust gases, causing the system to shut down for safety.
E40 High Your boiler has detected an issue with the sensor that monitors the temperature of the water coming back from your radiators, preventing the system from running efficiently or at all.
E53 High Your boiler is struggling to breathe properly because the exhaust pipe outside might be blocked or the gas is not burning correctly, causing the system to shut down for safety.
E55 High Your boiler has lost its fine-tuning and needs to undergo a self-calibration process to ensure the gas and air are burning efficiently.
